A weak battery rarely fails at a convenient time. Tire Taxi eliminates stranded moments by bringing full battery diagnostics and replacement directly to your driveway or office. Using digital load testers, we assess the current battery’s capacity, alternator output, and starter draw. If a replacement is required, we select an OEM-recommended battery, maintain computer settings with a memory-saver, and swap the unit while cleaning terminals and applying corrosion inhibitor. We then perform a final system test to ensure the alternator is charging correctly. Our service saves you from towing fees, dealership upcharges, and lost productivity—providing peace of mind that your vehicle will start every time.
